Apparatus and method for sinus lift procedure

Abstract

An osteotome for sinus lift procedures includes a body interchangeable with various handles. The body includes a shaft that is releasably received into the handle, and a tip portion. The tip portion may be directly utilized for ridge expansion / bone compression, or a succession of tip members may instead be received thereon to provide suitable diameter escalation to create the socket. A conduit in the tip portion interconnects with a conduit in a hydration port and a conduit in a tip member. A hose couples the hydration port to a syringe, to deliver fluid out the tip member to lift the membrane. Graduated syringe markings permit delivery of measured fluid quantities to control the amount of lift. A second hydration port is coupled to a graduated cylinder through a valve, which is opened after lifting is complete, to measure the fluid released. A loss of fluid measured indicates a sinus tear.

CROSS REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority on U.S. Provisional Application Ser. No. 61 / 674,121 filed on Jul. 20, 2012, the disclosures of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to improvements in Osteotomes for performing crestal approach sinus lift procedures, and more particularly to improvements that reduce the number of separate tools that must be obtained and utilized by the dental specialist, as well as improvements that better facilitate completing the procedure more safely.BACKGROUND OF THE INVENTION[0003]There are many conditions which may result in a person becoming partially or completely edentulous (periodontal disease, an injury, etc.), which in the past had been remedied by the wearing of a prosthetic device, known as dentures. Dentures were constructed to replace the missing teeth and were supported by surrounding teeth and / or by the underlying tissue. The significant dra...

AI Technical Summary

Benefits of technology

[0014]It is another object of the invention to provide a means of supplying a measured amount of saline solution within an implant hole to more safely cause lifting of the schneiderian membrane.

[0016]It is a further object of the invention to provide a means of quickly comparing the amount of evacuated saline solution with the amount of solution originally delivered through the implant hole to raise the sinus membrane.

[0018]It is a further object of the invention to provide an improved Osteotome which is adapted to receive various geometry nozzles, to allow gentle separation of the sinus membrane.

[0023]It is an object of the invention to provide an improved Osteotome that reduces the number of handles required, by permitting various sized conical expansion tips to be releasably secured in a specially adapted handle.

Problems solved by technology

However, the subperiosteal implant technique is seldom used today.

However, the alveolar bone quickly becomes atrophic in the absence of teeth, resulting in lack of available bone.

The technique causes expansion of the pilot hole without further elimination of bone material, and generally compresses the bone and increases bone density, in the surgeon's favor.

Further use of successively larger Osteotome tools causes lateral compression that increases bone density and the size of the opening.

There are many steps taken during the performance of this procedure during which serious damage may be caused to the patient's physiology, particularly with respect to the sinus membrane.

Puncturing of the membrane is a serious complication, which may be worsened by the introduction of bone particles therein, and the contracting of a fungal infection could furthermore be fatal.

In addition, when a perforation occurs, the bone particle may lead to blockage of the osteum and cause sinusitis.

Membrane repair during the crestal approach is very difficult to achieve.

The prior art Osteotomes have sought to improve the procedure, but are nonetheless still lacking.

. . with different styles and sizes” may be replaceable “by a mechanical manner such as screwing.” While constituting an improvement, it does not go far enough to assist the oral surgeon seeking to perform implant surgery on a patient in a brief amount of time, and in the safest manner according to his / her own physique and preferences.
